MACHINE FOR COATING OR IMPREGNATING BAGS WITH WAX.

SPECIFICATION forming part of Letters Patent No. 403,295, dated May 14, 1889.

Application tiled March 20, 1888. Serial No. 267,793. (No model.)

vT0 all whom it may concern- Be it known that I, ADoLPH SEGAL, a subject of the Emperor of Austria, residing at Camden, New Jersey, have invented certain Improvements in Machines for Coating or Impregnating Bags with lVaX, of which the following is a specification.

The object of my invention isto effect the rapid coating or saturating with wax of bags or like articles made of paper or other material; and this object I attain by the mechanism hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l represents in longitudinal section a machine constructed lfor carrying out my invention; and Figs. 2 and 3 are diagrams showing certain modiiications in construction.

A is the supporting-frame of the machine, having opposite standards a slotted for the reception of the boxes for the journals of upper and lower hollow rolls, B B which I term the coating-rolls, said rolls being heated by steam or in any other equivalent manner, and the upper roll being adjustable from and toward the lower roll by means of adjustingscrews b. In bearings in other standards, d, are free to turn the journals of similar hollow heated rolls, D D', which I term the transfer-rolls,and all four of these rolls are so geared together as to rotate at the same surface speed, the dotted circles in Fig. l representing spur-gearing and the shaft of the roll B being` geared to the shaft of the roll D by chain belt and sprocket-wheels, as shown in said figure. In bearings in the standards are also free to turn the journals of rollers ff and g g, while other rollers, z' t', and

on m, are carried, respectively, by the opposite arms of stretching-levers I and M, pivoted to bearings on the standards d.

Around the upper roll, B, passes an apron, J, which, after passing beneath the roll, passes over the top of one of the rollers f, thence beneath the roll D, thence over the roll D, thence between the rollers g g, thence around and between the rollers t' i, and thence back to the top of the roll Bgand a lower apron, J', takes a substantially similar course with reference to the lower roll, B', passing from the top of said roll beneath the lower roller, f, thence beneath the roll D, thence over the roll D', thence between the rollers g g, thence around and between the rollers m nu, and thence over a guide-roller, n, to and around the bottom of the roll B. The lower portion of said roll B is contained in a trough, F, mounted on the frame A, an d this trough contains a supply of parafiine or other wax, which is maintained in a melted condition 'by a steam-coil, z, in the trough orby other suitable means. As the various rolls are rotated, therefore, in the direction of the arrows shown in the drawings, the aprons J J are caused to travel in the direction pointed out, and the lower apron, J', is caused to pass through the melted wax in the trough F, so that it becomes thoroughly coated with the wax, and by contact with the upper apron, J, serves to likewise coat the same.

The rollers f f are spreaders-that is to say, they serve to distend the aprons at a point between the rolls B B and the roll D-and into the opening thus provided are inserted in succession the bags to be coated or saturated with wax, these bags being deposited upon the lower apron, J and being carried forward by the same to the roll D, where they are confined and subjected to pressure between the two aprons and carried around the roll, and thence up to and around the roll D, from which they pass to and between the delivery-rollers kg g, and are discharged onto a carrier-apron, N, by which they are conveyed to a suitable receptacle located at such a distance from the rollers g g that the bags will be properly cooled in their passage.

The heat of the rolls D D and the pressure of the aprons cause the wax on the adjacent faces of the aprons J J to adhere to or permeate the paper, textile fabric, or other material of which the bags are composed, so that the wax will be transferred from the aprons to the bags, and the latter, when delivered from the rollers g g, will be properly coated or impregnated with the wax.

h [yinventiomas will be evident, is not limited to the waxing of bags, but may be applied to the waxing of other articles, or even of separate sheets of paper when the. latter is 'such that it cannot be conveniently treated in continuous lengths.

Various modifications in the construction of the machinery for carrying out my inven- IOO tion are possible, and in Fig. 2 I have shown an instance of a modified form of machinein which a single transfer-roll only is used, one of the delivery-rollers and one of the spreader-rolls being also dispensed with, and the wax being applied directly to both of the aprons, and in Fig. 3 I have shown a further modification, in which the wax is applied to the upper apron from a trough, s, above the roller B, through a strip of felt or like material, the bag or other article being fed in between the aprons J J and where they are spread apart, and then confined and subjected to pressure between the same until it is discharged from the rollers g g.

I do not claim in this application the pro- Cess of making` waxed bags by first forming the bag in the ordinary way and then coating or impregnating it with wax, as this forms the subject of a separate application filed by me on'the 7th day of January, 188i), Serial No. 295,675.

Having thus described my invention, I claim and desire to secure by Letters Patentl. The combination of the two aprons, rolls foi-guiding and feeding the same, means for applying wax to the contiguous faces of the aprons, and a spreader for separating the aprons after they have been waxed, so that the bags can be inserted between them, substantially as specified.

2. rlhe combination of the two aprons, rolls for guiding and feeding the same, means for applying wax to the contiguous faces of the aprons, and one or more heated rolls for imparting pressure to the waxed aprons after the bags have been inserted between them.

3. The combination of the two aprons, rolls for guiding and feeding the same, means for applying wax to the contiguous faces of the aprons, a spreader for separating the aprons after they have been waxed, and one or more heated press-rolls for acting upon the aprons after the spreading of the same, all substantially as speciiied.

1I. The combination of the two aprons, heated rolls around which said aprons pass, means for applying wax to the aprons as they pass around said heated rolls, rolls for holding the aprons in contact with each other after they have passed around the heated waxing-rolls, and means for imparting movement to the rolls, so as to cause the traversing of the aprons, substantially as specified.

5. The combination of the two aprons, guiderolls therefor, heated waxing-rolls, one or more p ress-r0lls, means for applying wax to one of the aprons as it passes around its heated waxing-roll and before it comes in contact with the apron passing around the other wa ing-roll, a spreader for the aprons, located between the waxing-rolls and prcss-roll, and means for driving the rolls so as to traverse the aprons, substantially as specified.

In testimony whereof I have signed my nam e to this specification in the presence of two subscribing witnesses.

AD OLPII SEGAIJ.
